BLS Factory Breitling Aviation Chronograph Perpetual Calendar Review
The BLS Factory has established a strong reputation in the watch market for delivering timepieces that combine precision, design, and value. One of their most impressive creations is the Breitling Aviation Chronograph Perpetual Calendar, a that embodies the spirit of Breitling's legendary Navitimer line. This detailed review examines the 41mm black-dialed mechanical watch, offering insights to help you decide if it merits a place in your collection.
Design and Dial
The watch features a round stainless steel case measuring 41mm in diameter, protected by a scratch-resistant sapphire crystal. The black dial is clean and highly legible, drawing inspiration from Breitling's aviation instruments. Subdials for the chronograph and perpetual calendar are thoughtfully arranged, enhancing the tool-watch aesthetic. The solid caseback provides durability, while the overall casual style makes it versatile for both daily wear and special occasions.

Movement and Perpetual Calendar
At the core of this lies a mechanical movement that powers time, date, chronograph, and perpetual calendar functions. The perpetual calendar automatically adjusts for varying month lengths and leap years, mirroring the behavior of the genuine Breitling. While replicating a perpetual calendar is complex, the BLS version is engineered for reliability with minimal adjustments required, showcasing the factory's meticulous attention to detail.
How the Perpetual Calendar Operates
Unlike simple date complications, the perpetual calendar eliminates the need for manual corrections for months with 30 or 31 days, as well as for February in leap years. The BLS movement replicates this seamlessly, making it a practical and impressive feature for collectors who value horological complexity.
Chronograph Function
The chronograph is a key feature of any aviation watch. This BLS offers start, stop, and reset functions via two pushers on the right side of the case. The central seconds hand serves as the chronograph hand, while the subdials track elapsed minutes and hours. The action is crisp, and the reset snaps back to zero cleanly, indicating high movement quality.
Strap and Comfort
The watch comes with a brown leather strap that complements the black dial beautifully. The leather is supple and requires a short break-in period, after which it conforms comfortably to the wrist. The stainless steel buckle features a Breitling-style logo engraving. For a different look, the 20mm lug width allows easy strap changes to NATO or mesh options.
Authentic vs. Replica: Identifying a Quality BLS Clone
- Weight: Genuine Breitling Navitimer uses heavier materials; quality clones like BLS use stainless steel with similar weight.
- Crystal: Sapphire with anti-reflective coating on the clone — test by tilting the watch; real sapphire reflects minimal light.
- Movement Finishing: Check the decorated rotor through a display caseback (if available). BLS often plates the movement to resemble Swiss ETA or Breitling calibres.
- Perpetual Calendar Operation: A functioning perpetual calendar that advances correctly is a hallmark of this clone. Be cautious of cheaper versions with only a simple date.
- Price: Genuine Breitling costs thousands; a super clone like this typically ranges from $200 to $500. If the price is too low, it likely indicates a low-quality replica.
Who Is This Watch For?
This BLS Breitling is perfect for enthusiasts who admire the aviation-inspired design and complex complications without the hefty investment of a genuine piece. It appeals to pilots, collectors, and anyone seeking a robust everyday watch with a story. Its casual versatility allows it to pair well with jeans and a button-down or a smart blazer.
Styling Suggestions
The black dial and brown leather strap form a classic combination. For a sportier look, swap the strap for a black rubber or steel bracelet. Avoid formal tuxedo events—the chronograph pushers and thickness mark it as a tool watch, best suited for business casual or casual settings.
